| Abstract: | The quaternary mixed anion of rare earth with 2,3-dimethoxylbenzoic acid and 1,10-phenanthroline has been synthesized from the water-ethanol solution. Elemental analysis shows that the complexes general formula is RE(2,3-DMOBA)2NO3Phen (RE = La, Nd, Eu, Dy). The complexes are characterized by IR, UV, TG-DTA analysis. Nu2 + nu5, nu2 + nu6 of NO3- are observed in 1772 and 1737 cm(-1) in IR spectra of complexes, it shows that NO3- group is in a bridging-chelating mode in which two O atoms chelate to RE3+ ions. UV spectra of ligand and complexes are different, it shows that ligand 2,3-dimethoxylbenzoate and 1,10-phenanthroline coordinate to RE3+ ions. Visible absorption spectra of Nd(2,3-DMOBA)2NO3Phen show that hypersensitive transition of neodymium. |
